[0232] 1. Preparation of (R)-(1-Azidoethyl)benzene(1-2)

[0233]

[0234] In an ice-water bath at 0°C, 1-1 (20g, 164mmol) and PPh 3 (85.9g, 328mmol) was dissolved in THF (300mL), then a THF (50mL) solution of DEAD (57.1g, 328mmol) was added dropwise, added dropwise to the system at a rate of 10mmol / min, and then DPPA (54.1g, 197mmol ) was added dropwise to the system at a rate of 6 mmol / min, and after the dropwise addition was completed, it was slowly raised to room temperature and stirred overnight. After the completion of the reaction was monitored by TLC, saturated saline (150mL) was added to the reaction system, extracted with n-hexane (3×50mL), separated into three layers, the uppermost layer was collected, and the uppermost organic phase was combined with saturated saline (50mL ), dried over anhydrous sodium sulfate, suction filtered, and concentrated under reduce...

[0244] 1. Preparation of Compound A

[0245]

[0246] At room temperature, the LiOH.H 2 O (220mg, 5.24mmol) was added to compound 1 (643mg, 2.62mmol) in MeOH / THF / H at one time 2 O (3mL, 1 / 1 / 1) solution, stirred overnight at room temperature. After the completion of the reaction was monitored by TLC, the reaction solution was concentrated, and water (10 mL) was added to the system. After adjusting the pH to 4-5 with 1N hydrochloric acid, it was extracted with dichloromethane (3×15 mL), and the combined organic phases were washed with anhydrous sodium sulfate Drying, suction filtration, and concentration under reduced pressure gave white solid Compound A (545 mg, yield 96%).

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a class of polysubstituted triazole carboxylate derivatives with novel structures, and the use of such compounds in the preparation of drugs with sedative, hypnotic and / or general anesthesia and drugs capable of controlling status epilepticus application in medicine. Background technique [0002] An imidazole derivative etomidate, the chemical name is R-(+)-1-(1-phenylethyl)-1-hydro-imidazole-5-ethyl carboxylate, which is a hypnotic intravenous general anesthetic , with a wide range of safety, it was once one of the commonly used drugs for anesthesia induction. The clinical application of imidazole derivatives has a history of 30 years (Br J Anaesth.1976; 48 (3): 213-6. PubMed: 1259887; Arch Int Pharmacodyn Ther.1975; 214 (1): 92-132. PubMed : 1156027; AcadEmerg Med. 2006; 13(4):378-83. PubMed: 16531603). Etomidate is a non-barbiturate intravenous sedative drug, i...
